Methods used. 50 households per wetland were interviewed to understand the wetland dependence and validation process. TEEB = The Economics of Ecosystems and Biodiversity

Study areas: urban and periurban areas were demarcated for the study (roughly 30 km) but also taking into account the urban sprawl

Satellite images used to spot the wetlands. The size class was defined, based on the resolution.

Kolkata: Over 389 wetlands subjected to a rapid assessment first: 30 urban and 7 periurban wetlands were scored for ES. Nagpur 12 (4 were periurban). Presence was scored as 1, summed to give the final score.

Introduction: Wetlands in India
• A wealth of ecosystem service benefits
• Inadequate attention in the national water sector
agenda
• Urbanization, population increase, land-use
changes have impacted
• Emphasis has been on ecologic and limnologic
studies
• Hydrological, landscape and wetland spatio-
temporal change analysis studies are sparse

Wetland Selection and Field Surveys (HH & FGDs)
Ecosystem Services
Check-listing / Scoring
Wetland Selection based
on ES Score & Community
dependence
Questionnaire Preparation,
Validation, Revision and
Field Surveys.
For each of the ES identified, a score of 1 was given and summed-up to give a
final score for the wetland.

Results from Kolkata 2/2
• 50% reduction in wetland area over a 12 year
period
• 37 wetlands were scored for ES. 30 in urban and
7 periurban
• Number of reported Ecosystem Services (ES)
varied between 4-20 per wetland
• High number of ES provided by a majority of
wetlands (75% fell within 15-17 range)

15.
Results - Nagpur 2/2
• 90% of wetland area were tanks and reservoirs
• 0.4% were classified as natural
• Loss of natural tanks (70%) was significant (was
obscured by water in quarries)
• ES scores varied from 15-23, and the
distribution was very similar that found in Kolkata

16.
Conclusions
• Wetlands in Kolkata and Nagpur support a rich
diversity of ES
• No other studies available on wetland spatio–
temporal changes that can evidence wetland losses
• Wetland conservation plan is necessary (Wetland
conservation policy drafted but not implemented)
• Engagement of decision makers and users is
important to develop policies that are relevant to
wetland conservation.
